To all whom it may cone em:

Be it known that I, ALLAN C. SHAVER, a. subject of the King of Great Britain, and

resident of the city of Montreal,.in the Prov-- inceof Quebec and Dominion ofCanada,

have invented'certain' new and useful I'mprovements inCompositions for Removing Rust from Fabrics, of which the following is a full, clear, and exact description.

This invention relates to improvements in method of and composition for'removing rus't from fabrics, and the object of the invention is to provide for the removal of rust very quickly and easily and without any damage to the fabrics. v

I According to the present invention, the stained portion of fabrics is saturated with a composition containing oxalic acid and oil Gaulth'eria, and is then subjected to a jet of steam, with the result that the stain is removed immediately and without any damage to the fabric. As soon as the'stain is completelyeradicated, the fabric is thoroughly rinsed in clean water. The oil'exerts a soft- 2 ening influence on the stained portion of-the fabric as well as a protective influence on the fabric itself, so that the oxalic acid may remove the stain without danger to the fabric. The action. of the acid is imperfect without the application of steam.

' The composition used comprises preferably by weight:

Water i 94% Oxalic acid 5Z Oil Gaultheria 1% The amount of oil used in proportion to the acid may be considerably increased or decreased but approximately the percentage above indicated will be most satisfactory, as it provides sufiicient oil to soften and rotect vantage of t e stronger solutions is that they containing oil Gaultheriai.

the fabric without providing an excess of oil. The amount of acid-used in proportion to water may also be considerably increased or decreased. Acid may be used suificient to make a substantially saturated solution which is about 11%, but with the stronger acid solutions agreateramount of oil should be used to rotect the fabric. The disadare somewhat dangerous in the hands of an unskilled person and that more careful andv thorough rinsing is required to remove the acid from the fabric.

Having thus described by I claim is; a p

1. A composition fcr removing rust stains from fabric containing oxalic acid and oil Gaultheria.

2. A composition for removing rust stains from fabric; comprising an aqueous solution of oxalic acid containing a small amount of oilGaultheria.

3. A composition of matter for. removing rust stains from fabrics, containing oxalic as acid. and approximately one-fifth of the weight of the acid of oil Gaultheria.

v 4. A composition of matter for removing rust stains comprising an aqueous solution of oxalic acid containing approximately 1% by weight of .oil Gaultheria.

5.- A composition of matter for removing. rust stains from fabric, containing an unsaturated aqueous solution of oxalic acid invention, what 6. A composition of matter for removing rust stains from fabric,- comprising by weight'approximately 9d% of water,"5%i.of oxalic acid and 1% of oil Gaultheria. I i

In witness whereof, I have hereunto set so my I
